THE FISHERY
The Colorado River at Hot Sulphur Springs offers anglers a classic Colorado fishing experience, with cold, clear waters teeming with trout and surrounded by the scenic beauty of wide meadows and mountain views.
Fish Species
The Colorado River at Hot Sulphur Springs is home to wild brown trout and rainbow trout, with browns being the more dominant species. Trout in this section typically range from 12-18 inches, though there is potential to catch larger fish, particularly during the fall when brown trout become more active as they approach their pre-spawn phase.
Unique Fishing Conditions
This section of the Colorado River offers a mix of riffles, runs, and deep pools, providing a variety of water types for different fly fishing techniques. Late spring through fall is prime fishing time, with summer hatches of caddis, blue-winged olives, and stoneflies offering excellent dry fly opportunities. Nymphing with midge, caddis, and stonefly patterns (sizes 16-20) is highly productive year-round, especially in deeper runs. Streamer fishing can also be effective, particularly in the fall when targeting larger browns.
Access and Regulations
Public access is plentiful along this stretch, with several access points through the Hot Sulphur Springs State Wildlife Area and nearby parks. This section is designated as Gold Medal Waters, meaning it is managed for trophy trout, and anglers are required to use artificial flies and lures only. Catch-and-release practices are encouraged to preserve the fishery, and it’s important to respect regulations that protect this valuable section of the river. Checking flow conditions is advised, as water releases from upstream reservoirs can influence fishing conditions.
TACTICS
AvidMax encourages anglers to explore their full repertoire on the Colorado River:
Nymphing
Nymphing allows anglers to target trout feeding below the surface, with or without an indicator, making it an effective technique for covering deep runs and slow pools where fish are actively feeding on subsurface insects.
Dry Fly Fishing
Fishing with dry flies provides the ultimate surface experience, imitating adult insects and offering exciting visual strikes, particularly during hatches when trout are feeding on the water’s surface.
Streamer Fishing
Using streamers mimics baitfish and other larger prey, offering an aggressive approach that can entice bigger, predatory trout, especially when fishing deeper water or fast-moving currents.

SEASONS
Each season on the Colorado River brings unique joys and challenges for AvidMax anglers:
Spring
Spring runoff raises water levels, making nymphing with stoneflies and San Juan worms effective in slower water along the banks. Focus on deep runs and eddies where trout hold during higher flows.
Summer
Summer brings prolific hatches of caddis, PMDs, and terrestrials like hoppers, offering excellent dry fly fishing. Early mornings and late evenings provide the best opportunities for surface action in riffles and along the edges.
Fall
Fall is a great time to target aggressive brown trout during their pre-spawn, with streamers and egg patterns being particularly effective. Look for trout in deeper pools and near structure as they prepare to spawn.
Winter
Winter fishing is slower but productive in deep, slow-moving water, where trout hold during colder months. Nymphing with small midges and baetis patterns works best during the warmest part of the day.

REMEMBER
The Colorado River at Hot Sulphur Springs offers anglers a serene and productive fishing experience, with cold, clear waters supporting healthy trout populations. However, its delicate ecosystem requires responsible fishing practices to preserve the beauty and health of this treasured fishery.
Water Conditions
The river can experience fluctuating flows depending on upstream releases and seasonal runoff. Be sure to check water levels before heading out, as higher flows can affect wading safety and fish behavior.
Regulations
Some sections near Hot Sulphur Springs may have specific catch-and-release regulations and tackle restrictions. Familiarize yourself with these rules to ensure compliance and contribute to the sustainability of the fishery.
Safety
The riverbed can be rocky and slippery, making wading challenging, especially during high flows. Use proper wading gear, and be cautious in faster currents or deeper pools, particularly after rainfall or during runoff season.
